perkj efd902cb1d Revert of Switch to use SequencedTaskChecker instead of ThreadChecker where needed. (patchset #1 id:1 of https://codereview.webrtc.org/2149553002/ )
Reason for revert:
Breaks Chrome FYI

https://build.chromium.org/p/chromium.webrtc.fyi/builders/Linux%20Builder/builds/8187/steps/compile/logs/stdio

Original issue's description:
> Switch to use SequencedTaskChecker instead of ThreadChecker where needed.
> This cl is in preparation for https://codereview.webrtc.org/2060403002/ Add task queue to Call.
> In the coming cl the video_sender, and i420_buffer_pool will be used on a task queue and therefore SequencedTaskChecker is needed instead of a ThreadChecker.
